SCOURING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 748,786, dated January L5, 1904.

i Application tiled April 18, 1903. Serial No. 153,154.v (No model.)

To a/ZZ whom it may con/cern.-

Beit known that I, ADoLPn PIETscH, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Scouring- Machines; and I do hereby declare that the following is a full, clear, and exact descrip` tion thereof. l

My invention has especial reference to devices for use in the chemical cleaning of delicate fabrics and garments; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter in connection with the accompanying drawings and subsequently claimed.

In the said drawings, Figure l is a vertical central sectional view of my said device, taken on the plane indicated by the line 1 1 in Fig. 2. Figs. 2 and 3 are vertical sectional views taken, respectively, on the planes indicated by the lines 2 2 and 3 3 in Fig. 1. A

Referring by numerals to the drawings, l represents a suitable support, one of the legs of which (marked 2) is formed with a series of teeth or detente 3 3 in the inner edge thereof adjacent to its lower end, above which the said leg is provided with a pin 4, from which a spiral spring 5 extends to another pin 6 on the lever 7 of a treadle 8, which lever is pivotally secured, as shown at 9, to the opposite leg of said support, said lever 7 being thus held in engagement with one of the said teeth or detents 3.

Rising from the top of the support 1 andsecured thereto, as by bolts 10 10, are the uprightbox-frames 11 1l, formed with vertical central slots separated by cross-pieces 12 and having cap-pieces 13 secured in place by screw-bolts 14, said cap-pieces being shown as formed with central upper extensions,

lwhereby cams 15 are pivotally held thereto by pivot-bolts 16, said cams having lever-arms 17 united by a horizontal rod 18.

13 2O represent upper and lower journalboxes having vertical movement in the slots of the box-frames 11, springs 21 being interposed between the under surfaces of the boxes 19 and the upper surfaces of the cross-pieces 12a-nd springs 22 between the under surfaces of the boxes 20 and the upper surface of the support 1. The lower boxes 20 have screwbolts 23 projecting vertically from the tops thereof, with adjusting nuts 24 thereon, wherebywhen said bolts are turned the boxes 20, with which the bolts23 have threaded connection, are forced downward against the pressure of the springs 22 as the heads of said screw-bolts bear against the under surfaces of the cross-pieces 12. The upper boxes 19 carry a'horizontal revcluble shaft 25 and the lower boxes 2O a like shaft 26. 'lfhe boxfraine 11 at one end of the standard carries a stud 27, on which is mounted a pinion 28, which is in mesh with a gear-wheel 29 on the adjacent end of the upper shaft and with a gear-wheel 30 on the adjacent end of the lower shaft 26, the teeth of said gear-wheels and pinion being long` enough to always engage irrespective of the vertical adjustment or movement of the said shafts 25 26, and the shaft 26 carrying at its extreme end, beyond the gear-wheel 30, fast and loose pulleys 31 32 for belt attachment to any source of power.

33 represents a connecting-rod between the horizontal rod 1 8, which connects the two cams 15 and the lever 7 ofthe treadle 8.

The shafts 25 26 at their ends opposite the described gear-wheels carry brushes,(marked, respectively, 34 35,) which are secu red to said shafts, as follows:.The brush-holding ends of said shafts are reduced in diameter, and said brushes have each a hollow wooden core 36, in which is rigidly secured a metal sleeve 37, which is slipped upon the reduced end of the shaft and kept from turning independently thereof by means of the engagement of a piu 38 within a recess in the inner end of said sleeve 37. The extreme end of each shaft is still further reduced in diameter and threaded and projected through a hole in the otherwise closed outer end of the sleeve 37, and a washer 39, having sharp projections 40 on its inner surface, is then slipped over the y outer end of the shaft, with the said projections 40 forced into the end of the wooden core 36, and a nut 41 screwed on the threaded end of the shaft to hold thebrush rmly in place.

42 represents a close-ended hollow semicylindrical guard covering the upper part of the upper brush 34 to prevent the liquid and other material thereon from liying into the facev of theoperator, the said guard being IOO supported in position by an arm 4:3, secured to the guard and to the cap of the adjacent box-frame.

The operation of my device will be readily understood from the foregoing description of its construction, taken in connection with the accompanying drawings. The garment -or article to be cleaned is soaked in the desired chemical or cleaning fiuid, and then the machine having been adjusted to bring the brushes 34 35 the required distance apart the operator takes said garment or article and holds it between the said brushes and brings the latter closer together by foot-pressure on the treadle 8, and power being applied the brushes will be revolved, thoroughly scouring the garment or article with which they thus come in contact, the operator moving said garment or article to expose all portions of its surface to the action of the brushes, which are meanwhile being revolved in the same direction, while the opposed adjacent surfaces of the two brushes are always moving in opposite directions, and hence of themselves have no effect in moving the garment or article being cleaned. This is of the greatest importance in the successful operation of my device, inasmuch as this opposite movement of the brush-surfaces at their points of contact with the said garment or article insures that the full effect of said brush action will be uponthe desired portion of the garment or article while the latter is stationary, and thus this action can be continued for a longer or shorter period of time, as desired, in each instance, whereas if the brushes themselves revolved in opposite directions the garment or article would have a tendency to be carried through between them unless very tightly held by the operator, and this with fragile and delicate fabrics would be extremely objectionable and produce unsatisfactory results.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a scouring-machine, the combination with a suitable support, of box-frames mounted thereon; journal-boxes carried by said frames; a pair of shafts journaled in said boxes; brushes secured to said shafts at one end thereof; gearing connected to the other ends of said shafts for revolving both in the same direction, so that the adjacent surfaces of the two brushes shall always move in opposite directions, springs for moving one of said shafts away from the other, and means for moving the first-named shaft nearer the other.

2. In a scouring-machine, the combination with a suitable support,of box-frames mounted thereon; journal-boxes carried by said frames; a pair of shafts journaled in said boxes; brushes secured to said shafts at one end thereof; gearing connected to the other ends of said shafts for revolving both in the same direction, so that the adjacent surfaces of the two brushes shall always move in opposite directions; and springs for moving the journal-boxes of one of said shafts and the said shaft and brush carried thereby nearer to the other shaft and its brush, and cams for forcing the journal-boxes of the rstnamed shaft nearer, to the said other shaft.

3. In a scouring-machine, the combination with a suitable su pport,of box-frames mounted thereon; movable j ournal-boxes carried by said frames; springs for moving said boxes in one direction and means for moving them in the opposite direction; a pair of shafts journaled in said boxes, and carrying brushes at one end and gear-wheels at the other end; a pinion in mesh with said gear-wheels for revolving both in the same direction, so that the adjacent surfaces of the two brushes shall always move in opposite directions; and power-pulleys on one of said shafts.

4. In a scouring-machine, the combination with a suitable support, of longitudinallyslotted boxframes mounted thereon; centrally-disposed cross-pieces, dividing the slotted portions of the box-frames so as to constitute separate slots on each side of the said cross-pieces, movable journal-boxes in said slots; springs for moving said boxes in one direction and cams and adjusting-screws for moving them in the opposite direction; a pair of shafts journaled in said boxes, and carrying brushes at one end, and gear-wheels at the other end; a pinion in mesh with said gear-wheels for revolving both in the same direction, so that the adjacent surfaces of the two brushes shall always move in opposite directions; power-pulleys on one of said shafts; a rod connecting said cams; and a treadle-lever pivoted to said support, and linked to the rod connecting the cams.

5. In a scouring-machine, the combination with a suitable support, of vertically-slotted boxframes mounted thereon; upper and lower movable journal-boxes in said slots; springs for moving said boxes upward; adjusting-screws for moving the lower boxes downward; cams pivotally supported on said box-frames, in contact with the upper journal-boxes, and having lever-arms connected by a horizontal rod; upper and lower revoluble shafts journaled in said boxes, and carrying circular brushes at one end and gear-wheels at the other end; a stud on one of the box-frames, intermediate of the said shafts; a pinion on said stud in mesh with said gear-wheels; a spring-controlled treadlelever pivoted to said support, and a connecting-rod between said lever, and the said horizontal cam-rod.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in
